摘要： Eine Hydrolenkung für Kraftfahrzeuge weist eine Lenkhandhabe auf, die ohne Zwangskopplung mit zu lenkenden Fahrzeugrädern betätigbar ist. Dabei erfaßt ein Winkelsensor die Lenkbewegung und übermittelt diese an ein Steuergerät, welches einen Elektromotor ansteuert. Der Elektromotor übt ein Moment auf eine Antriebswelle (13) eines Lenkgetriebes zur Auslenkung der Fahrzeugräder aus. Zur hydraulischen Unterstützung steuert der Elektromotor ein Steuerventil (12) einer Hydraulikeinheit an. Die Antriebswelle (13) ist mit einem starr verbundenen Antriebszahnrad (6) und einem entkoppelten Abtriebszahnrad (7) zur Übertragung des Moments auf die Fahrzeugräder versehen. Die beiden Zahnräder (6,7) sind definiert zueinander verdrehbar. Ein translatorisch bewegbares Ansteuerglied (22) zum Auslenken des Steuerventils (12) ist sowohl durch eine sich mit dem Abtriebszahnrad (7) drehende Schrägführung (18) als auch durch eine sich mit der Antriebswelle (13) drehende Längsführung (19) derart geführt, daß eine relative Verdrehung der beiden Zahnräder (6,7) zueinander zu einer Verschiebung des Ansteuergliedes (22) in axialer Richtung der Antriebswelle (13) führt.

摘要： Pilot operated steering system with load-responsive flow amplified control system includes a directional control valve (19) movable to an operating position to direct fluid from an operating fluid circuit (16) through a variable orifice (75) to a steering motor (11) and to direct control fluid from a control circuit (17) through another variable orifice (74) to combine with steering motor fluid. Control fluid moves directional control valve (19) to an operating position. Pressure compensation creates a predetermined pressure differential across variable orifice (74). The steering control valve (24) controls the position of the directional control valve (19). Pump displacement (14) responds to pressure in control circuit (17) to establish a constant pressure differential between pump (14) and steering motor (11) load pressure. Relative size of the variable orifices determines the flow amplification ratio between the pilot control circuit and the power operating circuit.

摘要： A power steering system used for a vehicle, in which a booster (11), a direction control valve (12) and a hydraulic pump (13) are connected to a hydraulic circuit. A pressure oil setting valve (15) enables a compensating pressure oil the pressure of which is higher than a circuit pressure to he extracted on the upstream side of the direction control valve (12). When a steering wheel (51) starts being turned, the compensating pressure oil is injected into a pair of reaction force chambers (38, 39) in the direction control valve (12) in the turning direction by presssure oil injection valves (16, 17). When the steering wheel (51) is turned back, a compensating pressure oil is injected into these two reaction force chambers (38, 39) in the turned back direction by the pressure oil injection valves (16, 17). A reaction force regulating valve (18) is provided in a reaction force regulating passage (26) which allows the two reaction force chambers (38, 39) to communicate with each other, and a throttle is regulated in accordance with a vehicle speed. This enables a response characteristics control operation improving the response characteristics with respect to a steering input to be carried out properly, and a speed sensitivity control operation varying the steering power in accordance with a vehicle speed to be carried out properly.

摘要： Valve for controlling a power-assisted rack-and-pinion steering mechanism, of the slide-valve kind, whose slide member 11 moves along an axis different from that of the pinion 1 as a result of the axial movement of the pinion produced by the thrust exerted on it by the rack because of the inclination of its teeth, said slide member being connected to the pinion through a kinematic mechanism with a high transmission ratio consisting of a rubber ring, all outer surfaces of which are enclosed by rigid walls, a push-rod 10, and resilient means pressing one against the other said rubber ring, push-rod and slide member in such a way that the displacements of the slide member is given by the displacement of the pinion multiplied by the ratio between the area of the rubber exposed to the axial thrust acting on the pinion and the area of the cross-section of push-rod 10.

摘要： PURPOSE: A spool structure of a pressure controlling valve for a vehicle hydraulic steering servomechanism makes the flow of hydraulic pressure slow and reduces various noises by making a small diameter portion on the middle thereof and flattening the edges thereof. CONSTITUTION: A pressure controlling valve is operated according to vehicle speed when a left/right steering servo force is applied by a rotary valve(10) on running. Then, a spool(21) in a space portion is longitudinally moved and controls the flow rate from an inlet(23) to an outlet(24). Oil flowing toward a small diameter portion(21a) of the spool(21) is moved with a small incidence angle and along a first flattened portion(21b) and a second flattened portion(21c). Thus, no vortex flow is generated because a saturated vapor pressure(Pv) is smaller than a hydraulic pressure(Po) of an inner wall. Therefore, the generation of noises is prevented.
